Until recently the conglomeration of Cuban laws pertaining to what can be broadly classified as workers' rights was very detailed and confusing. Before the revolution, special interests (primarily one trade union or another) lobbied for legislation that would cover their particular problems or interests. For the most part this legislation remained on the books until the mid-1980s. The 14th and 15th congresses of the Central de Trabajadores de Cuba (Cuban Workers' Federation CTC), held in 1978 and 1984, as well as the 2d congress of the Cuban Communist party in 1980, recognized many problems with the old body of labor legislation and began to draw up specific plans to revamp it to make labor-management relations function more efficiently, productively, and justly under socialism. The most important proposed changes were discussed within the 2 million+ member CTC before approval by the National Assembly in 1984.

One of the most important jobs of Cuban unions today is protecting the class interests of the proletariat against its employers (state enterprises). In specific terms this means enforcing the Labor Code, which exists to protect the rights of individual workers and of the proletariat as a whole. The Cuban
